"Each" refers to a group, but the focus is on the individual. This word is also used as a pronoun. "Each student recieved an A" "Every" refers to a group and does not consider members of the group as individuals. "Every" cannot be used as a pronoun. "Every student recieved an A" I copied an example from an online source for more clarification. "Each child was reading a different book" (dissimilar action) "Every child was reading a book." (similar action) https://linguapress.com/grammar/points/each-every.htm "Someone" and "somebody" have no difference. "Someone" is more commonly used.

Each v Every This is quite a technical question so the difference is not always obvious and is frequently confused by even native speakers. It sort of depends on whether you are referring to a singular or the plural. As a general rule "every" means "one of the group or collective" when all individual members of the group can be lumped in together and "each" means "one of the group or collective" when you want to acknowledge its difference from other members of the group. "Every member here should have an envelope on their chair" "Each member who has a yellow envelope on their chair should make their way to the front desk" "I eat an apple every day" "I eat an apple each day I go to work"

Great question! every and each: For the *most* part, we use 'every' more often. If you are unsure which to use try using every and ask the person you are speaking with if you were correct. 'Each' implies singling out one item one by one, whereas 'every' is used more generally. However, native English speakers use them interchangeably and the difference is very subtle. Again, try using them more often with native speakers and ask them how you can improve. As for 'someone' and 'somebody' the difference is even more subtle. Perhaps none at all. I use both in my speech and to choose which one I use it usually has to do with which one sounds better. 'Someone' and 'somebody' mean the same thing and you can choose which one you prefer by personal preference. 'Someone' is slightly more formal, so I use this more when I'm trying to be very polite or sound well educated. Other than that they mean exactly the same thing! I hope this helps! CE
